DO-254 Training

RTCA is hosting a three-day training course, tailored specifically to design/verification engineers and project/certification managers requiring DO-254 compliance.

Conducted by Randall Fulton/Roy Vandermolen, experienced consultants, FAA Designated Engineering Representatives (DER), and author, this three-day course will:
  • Provide an overview and application of RTCA DO-254, as defined by current FAA and EASA guidance in airborne electronic systems.
  • Describe how to apply the DO-254 lifecycle and supporting processes, understand system safety assessments and the design assurance level (DAL), set up a project correctly through proper planning and standards.
  • Present techniques for writing requirements for electronic hardware and how to optimize requirements for the verification processes.
  • Describe how to efficiently and effectively verify requirements with simulation and hardware test.
  • Address specific considerations, for programmable logic devices (PLDs) such as FPGA/ASIC versus all electronics, commercial off-the-shelf (COTS) components usage, and tool assessment and qualification.

  Mr. Randall Fulton is an FAA Consultant DER with 37 years of Electrical Engineering experience emphasizing software and electronic hardware development and verification. Mr. Fulton has a BSEE from the Pennsylvania State University and earned his FAA Designated Engineering Representative (DER) credentials in software and programmable logic devices (PLD) while working at Boeing Commercial Aircraft. As a DER, Mr. Fulton has had approval authority for PLDs since 1997 and has worked numerous Part 23 and Part 25 certification programs with field programmable gate arrays (FPGA), application specific integrated circuits (ASIC) and software. He currently works as a Consultant DER through SoftwAir Assurance, Inc.

Mr. Fulton, along with Roy Vandermolen, taught the DO-254 practitioners course for RTCA in Washington DC from 2006 to 2009. Mr. Fulton is also an instructor for the Airborne Electronic Hardware Job Functions class for the FAA at the FAA Academy in Oklahoma City.

Randall’s DO-254 projects include programmable logic devices used in the flight controls and environment controls for the Learjet model 200 aircraft, system and device level DO-254 compliance for the primary flight controls actuation for the Boeing 787-8, lateral control electronics for the Boeing 747-8, input/output modules for Rockwell Collins ProFusion integrated modular avionics (IMA), and data packages for commercial off the shelf graphics processors used in display systems.

Randall is co-author of the new book Airborne Electronic Hardware Design Assurance: A Practitioner's Guide to RTCA/DO-254 published by CRC Press in December, 2014. Randall also wrote the DO-254 chapter as a contributing author for the updated Digital Avionics Handbook, Third Edition published by CRC Press in September, 2014.
